For a flat-panel TV without regular contact with ordinary consumers, prior to purchase flat-panel TV will have a question: " is to buy an LCD TV or Plasma TV is good and what difference does it both ? ? "
From now on, LCD TVs and plasma TVs are the mainstay products in the field of flat-panel TVs , both have their own strengths , competing with each other , have their own space for development , especially with the development of flat panel technology , plasma Resolution reach high standards, bigger and expensive LCD TV , motion picture tailing serious problems have been overcome , the difference is narrowing.
A technical comparison
Of course, from a technical point of view , there are still some differences between the two . Such as high-definition LCD TV image , body thinner, more stylish and beautiful ; Tsingtek 128x64 lcd
display plasma in brightness, color , layering , and so has certain advantages. Here we were to look at the technical characteristics of both understanding :
LCD technology principle: a liquid crystal projection display (Liquid Crystal Display, LCD) LCD is a rearward light-emitting fluorescent tubes , then through a set of lenses and turbot backlight module , the light is uniformly transmitted to the front , in accordance with the received video signal , the liquid crystal liquid crystal molecules within the pixel layer of the glass should be arranged relative to which the light is deflected or barrier to be determined .
Plasma Technical principle: the light-emitting principle of plasma display (Plasma Display Panel) PDP is to inject an inert gas or mercury gas in the glass tube , using a voltage mode , the gas generating a plasma effect , emit ultraviolet light, the individual RGB three excitation type fluorescent body have different primary colors visible by using the length of time to generate the excitation of different brightness.
2 , the dynamic contrast resolution
During the discussion , such as whether to buy an LCD TV or plasma TV, a dynamic definition of a contrast is also very important items. General speaking , the dynamic definition refers to the moving image during playback screen resolution , sharpness, dynamic screen presence embodied in the "tail " , the impact of presence and overlapping . This depends mainly on the TV itself, the response rate, response speed should be noted that this concept is generally concerned for LCD TVs .
LCD TVs currently on the market , the response time is generally 4-8 ms encountered rapid screen ( fast motion such as soccer , racing, etc. ) , it will produce smearing . However, with the advent of 100Hz/120Hz even 200Hz/240Hz multiplier technology, smearing improved, but limited by the working principle , trailing difficult to eradicate the problem . For plasma TV , the response speed of up to 2-3 microseconds Tsingtek low
temperature 240x128 lcd, 1-3 microseconds with traditional CRT flat , beyond the scope of the human eye can recognize completely negligible .
In LCD and plasma performance synchronous upgrade stage, we still have to choose according to their needs , after all, is the best fit . If you are a hardcore amateur sporting events , or to vote for a big plate plasma care of yourself aesthetic movement concept, but also pay attention to their energy problems , after all, is the long-term benefits of energy-saving , energy-saving recommendations must purchase a plasma . If the pursuit of fashion and aesthetic quality , it can be carefully selected in numerous boutique in LCD .
Access to information mainly through display and interactive interface with the electronic technology and electronics integrated rapid development of LCD modules in the smart instrumentation to achieve a mix of graphics and text display, man-machine dialogue to achieve the on-screen menu operation thus graphic LCD module with its small size, low power consumption, the development cycle is short, safe, reliable, flexible, etc., in the smart meter has been more widely used.
